I'm currently a biochem major so I need to take 2 quarters of pchem at my school. I have the choice of taking the "pchem for engineers" series or the "pchem for bio majors" Apparently the pchem for bio majors series (CHE107A/107B) is a 2 quarter series while the one for engineers is 3. I also heard that che107a/b is pretty "watered down" and in a way, similar to gen chem. While the other pchem courses are much more intensive and math based. Should I opt for the easier pchem series? Is there a reason why I should take the harder pchem courses?
